Title: Absorption
IPC: B01D53/14
Filed: 1970-04-29
Abstract: 1308197 Regeneration of absorptive liquor VETROCOKE COKAPUANIA SpA and G GIAMMARCO 29 April 1970 [2 May 1969] 20717/70 Heading C1A The invention comprises a process for regenerating an absorptive liquor which has been used to remove CO 2  and/or other acidic gases from a gaseous mixture wherein said liquor, at an initial temperature of at least 100 C., is depressurized, at least some of the vapour thus generated being caused to remain in contact with the liquor for a time no longer than that taken for the partial vapour pressure of the acid gas(es), e.g. CO 2 , in said vapour to become substantially equal to that of said gas(es) in the absorptive liquid. The advantage of the process of the invention lies in the fact that the prolonged contact between vapour and liquid enables the steam in the vapour to desorb more acidic gas from the liquor than is possible in simple "flash" procedures. In a preferred embodiment the depressurization is smooth and continuous. Thus in Fig. 2 the hot spent absorptive liquor is passed in series through a series of towers divided into zones by means which improve gas/liquid contact and at the same time prevent back mixing between said zones. As the liquor passes up each column the hydrostatic pressure decreases and hence vapour is smoothly and continuously liberated within the body of said liquor. The vapour liberated in each column is removed from the head of each of said columns. In a further embodiment illustrated in Fig. 6 spent absorptive liquor is removed from the base of absorber A and is partially regenerated in a known type of regeneration column R fitted with a reboiler r<SP>1</SP>. The hot, partially regenerated liquor leaving said column R is further regenerated in a column V by the process of the invention, depressurization being again due to decrease in hydrostatic pressure and the liquor from tower V is then returned to absorber A where it is used to remove further acid gases from gas mixtures.

Title: Improvements in or relating to electric hybrid devices
Inventor: HICKIN ERNEST MALCOLM
IPC: H03H7/48
Filed: 1954-07-15
Abstract: 770,317. Hybrid networks. GENERAL ELECTRIC CO., Ltd. July 8, 1955 [July 15, 1954], No. 20724/54. Class 40 (8). A hybrid device of the kind comprising a closed loop of transmission line to which connections are made at four spaced points is provided with a crossover between the conductors of the transmission line in order to reduce the physical distance between two of the connections. The device may be formed from a pair of brass blocks 41 provided with registering channels 43 in their mating surfaces. Supported within the channels are metal rods 14 forming the inner conductors of three coaxial lines of equal length. The fourth side of the loop is formed by a line comprising two conductors 44, 45, each of which is connected at one end to the inner conductor of a coaxial line and at the other to one of the brass blocks. The twoconductor line lies on the axis of a cylindrical cavity 46 formed within the brass blocks. The spacing of wires 44, 45 is of the order of a few thousandths of an inch and is obtained by winding first one of the wires with nylon thread and then winding a second layer of thread over both wires placed together. Input and output connections 1, 2; 3, 4 respectively, are made by means of short coaxial lines running through the brass blocks at right angles to the plane of the ring. The output lines are matched to the loop by means of short-circuited stubs 54, 55. The two outputs are respectively equal to the vector sum and difference of the inputs. A modification (Fig. 1, not shown), is described in which the twoconductor line is of the same length as the coaxial lines and is mounted in a spherical cavity. In this construction the input and output connections lie in the same plane as the loop. In a further modification the transmission line is of the kind comprising an inner conductor disposed between two parallel plane conductors. In the region of the cross-over extended portions of the inner conductor overlap and are connected at their ends each to one of the plane conductors in a similar manner to the conductors 44, 45.
